"We still hold out hope" - those are the desperate words of Irfon Roberts as he issues an emotional appeal for fresh information following the disappearance of his son Owain.

Thirty-six-year-old Owain hasn't been seen since 10th March. The last sighting of the musician was near his hometown of Cardigan, Ceredigion.

As Christmas approaches, Owain's father has spoken of how difficult a time it will be for the family - and how despite not having seen or heard from their son in nine months, they still hold out hope that he will return home safely.
